In this article, we will learn how to develop and run a python-Django app in less than 5 minutes.

Prerequisite: Python3.

Step to create and run the Django app:

Install the virtual environment. You may proceed without a virtual environment too, but in the long run, the virtual environment is going to be very helpful.

$ pip install virtualenv

Create a virtual environment.

$ virtualenv -p /usr/bin/python3 helloworld_VE

$ source helloworld_VE/bin/activate

$ pip install django

$ django-admin startproject myproject

$ cd myproject

$ python manage.py startapp helloworld

Add the below lines to this file and save it.

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
]

Open views file and save the below code in it. 

from django.shortcuts import render
from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello World. First Django Project. PythonCircle.Com")

Include the helloworld app's URLs in main project URLs file.

Open myproject/urls.py file and make add below line in urlpatterns.

url(r'^helloworld/',include('helloworld.urls')),

Also, import include module.

from django.conf.urls import include

Now finally add helloworld in installed apps in myproject/settings.py file.

Now start the Django development server by running the command. 

$ python manage.py runserver

This will run the python HTTP server on the localhost and 8000 port. If you want to run it on a different port, use port number in the command. For example $ python manage.py runserver 8888.

Use this command to make your project available for everyone on the network.

$ python manage.py runserver 0.0.0.0:8000

So this was a basic tutorial to set up a Django app in less than 5 minutes. You can refer to GitHub code and video.
